Main Application Scenarios of Fiber Connection Module
Ultra-Long-Haul Backhaul Networking: Connecting regional corporate offices, distributed campus networks, or government buildings spaced up to 100km apart without requiring intermediate signal regenerators.
Internet Service Providers (ISPs) & Telcos: Extending Gigabit Ethernet fiber links from central offices to remote aggregation points or rural broadband infrastructure.
Data Center Interconnect (DCI): Linking primary data centers with geographically separated backup or disaster recovery (DR) facilities.
Metropolitan Area Networks (MANs): Providing core high-bandwidth single-mode connections across municipal enterprise setups and smart city infrastructures.
Q1: What is the maximum distance supported by the Cisco GLC-EZX-SM-100 compatible SFP?
A1: It supports ultra-long-haul distances of up to 100 kilometers (62.1 miles) over standard single-mode fiber (SMF).
Q2: Do I need to use an optical attenuator with this 100km SFP module?
A2: Yes. If your actual fiber link loop is short (typically under 40–50km or experiencing less than 21dB of link loss), you must insert a 10dB to 15dB optical attenuator at the receiver side to prevent burning out or overloading the sensitive APD optical receiver.
Q3: Is the GLC-EZX-SM-100 hot-swappable?
A3: Yes, it is fully hot-pluggable. You can insert or remove the transceiver without shutting down the host switch or router.
Q4: What wavelength does the GLC-EZX-SM-100 use?
A4: It operates at a 1550nm wavelength, which is ideal for minimizing signal attenuation over long single-mode fiber spans.
Q5:Can I use this transceiver with standard multi-mode fiber (MMF) patches?
A5: No, it is strictly designed for Single-Mode Fiber (SMF) with a 9/125µm core size. It will not work over multi-mode fiber.
Q6: What is the difference between GLC-ZX-SM and GLC-EZX-SM-100?
A6: The GLC-ZX-SM typically supports distances up to 70km–80km, whereas the GLC-EZX-SM-100 features a more powerful laser and a more sensitive receiver engineered specifically to reach up to 100km.
